The sherpa.astro.optical module¶
Optical models intended for SED Analysis
The models match those used by the SpecView application [1], and are intended for un-binned one-dimensional data sets defined on a wavelength grid, with units of Angstroms. When used with a binned data set the lower-edge of each bin is used to evaluate the model. This module does not contain all the spectral components from SpecView ([2]).
